Hi Jeff! Appreciate the response! Adding this line to etc/hosts fixed the issue with uploading .fpg files to the red_pitaya.
I reinstalled casperfpga in the way you outlined, and the line last of the install reads "Finished processing dependencies for casperfpga==0.4.4.dev932+master.eac2d46", so it seems like now I have version 0.4.4. I am still having issues with the estimate_fpga_clock() function, however. It continues to read randomly changing values, all much higher than the 125 MHz I am expecting. Do you have any other suggestions for what might be wrong?

Hello Nitika, I’m not using conda environment so I can’t comment on that, but: 1. To clear the “Odd?” problem I ssh’d into red pitaya and added “127.0.0.1 localhost” line to etc/hosts on red pitaya. 3. To clear the “value seems to also be varying rapidly rather than incrementing steadily as expected” problem I updated casperfpga from version 0.1.1 to 0.4.4. This can be done by doing: ~/casperfpga$ sudo pip install -r requirements ~/casperfpga$ sudo pip install . instead of: ~/casperfpga$ sudo pip install -r requirements ~/casperfpga$ sudo pip install casperfpga i.e., doing it the first way installs from the local repo instead of the remote repo which I think contains an outdate version of casperfpga. You can verify your version is ipython by: In[x] casperfpga.--version-- (not sure I have the syntax exactly right) Hope that helps -- Jeff [cid:[email protected]] Jeffrey Kobesky Electronics Engineer Naval Research Laboratory Information Technology Division Code 5555 Bldg 1 Room 222 4555 Overlook Ave SW Washington, DC 20375 Office 202.404.7109 Mobile 443.243.1554 [email protected]<mailto:[email protected]> From: Yadlapalli, Nitika <[email protected]> Sent: Tuesday, January 25, 2022 6:34 PM To: [email protected] Subject: [casper] Red Pitaya programming/clocking issue? Hi all! I am getting started with casper on a Red Pitaya 125-14. I've been following the tutorial about using the ADC/DAC boards (https://casper-toolflow.readthedocs.io/projects/tutorials/en/latest/tutorials/redpitaya/tut_adc_dac.html) and have run into a few issues: 1. I'm not able to use upload the upload_to_ram_and_program method with the .fpg file. I get this "ERROR:10.42.0.69:10.42.0.69: no programming informs yet. Odd?" and I don't seem to be able to activate the tcpborphserver on the red pitaya either to fix it as I've seen in a previous archive thread. 2. 3. I can use the .bof file for programming the red pitaya, so I've been moving forward with that. If I try to get the clock speed, however, using estimate_fpga_clock(), the output estimated clock speed changes wildly with time and is never consistent with the 125 MHz speed I expect. Additionally, if I try to read the adc_samp_cnts register as outlined in the tutorial, the value seems to also be varying rapidly rather than incrementing steadily as expected. Has anyone encountered these issues before? I have all the packages installed in a conda environment.
